Checking and Filling
Motor compartment
General information
Special care is required if you are working in the
motor compartment
For work in the motor compartment, such as
checking and filling fluids, there is a risk of in-
jury, scalding, accidents, and burns. For this
reason, follow all the warnings and general
safety precautions provided in the following in-
formation. The motor compartment is a danger-
ous area in the vehicle. > A.

age component can result in a fatal electric
shock. The components in the high-voltage
system are marked with a warning label which
warns of the high-voltage.
— The voltage level in the high-voltage system
is still dangerous and potentially life-threat-
ening when the ignition is switched off.
— Never perform work on orange high-voltage
cables or on high-voltage components. Only
authorized repair facilities that are certified
may perform work on the high-voltage sys-
tem.


ZA WARNING
— Switch the ignition off.
— Set the parking brake.
— Select the “P” (Park) selector lever position.
— Keep children away from the motor com-
partment.
— Never spill operating fluids in the motor
compartment.
— Avoid short circuits in the electrical system.
— Never open the hood when there is steam or
coolant escaping from the motor compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
— Never open the cap on the coolant reservoir
if the coolant is hot. The cooling system is
under pressure.
— To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
thick cloth when opening.
— All work on the battery or electrical system
in your vehicle can result in injuries, chemi-
cal burns, accidents, or burns. Because of
this, all work must be performed only by an
authorized Audi dealer or authorized Audi
Service Facility.
— Limit your exposure to chemicals to as short
a time as possible.

ZA WARNING
California Proposition 65 Warning:
— Engine exhaust, some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of Cali-
fornia to cause cancer and birth defects and
reproductive harm. In addition, certain flu-
ids contained in vehicles and certain prod-
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproductive harm.
— Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harms.
Wash hands after handling.


ZA\ WARNING
The voltage in the high-voltage system is life-


threatening. Touching a damaged high-volt-

() Note
When filling fluids, be sure not to add any flu-
ids to the wrong reservoirs. Otherwise, severe
malfunctions and damage will occur.
@) For the sake of the environment
You should regularly check the ground under
your vehicle in order to detect leaks quickly. If
there are visible spots from oil or other fluids,
bring your vehicle to an authorized Audi deal-
er or authorized Audi Service Facility to be
checked.

the vehicle will be operated. If the coolant addi-
tive percentage is too low, the coolant can freeze
and cause damage.

additive tion
Warm min. 40% min. -13 °F
regions max. 45% (25°)
Cold min. 50% max. -40 °F

@) Note
— Before winter weather begins, have an au-
thorized Audi dealer or authorized Audi
Service Facility check if the coolant additive
in your vehicle matches the percentage ap-
propriate for the climate. This is especially
important when driving in colder climates.
— If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. Using other additives in-
creases the risk of damage. If this happens,
only use water and restore the correct mix-
ture ratio with the specified coolant additive
as soon as possible.
— Only refill with new coolant.
— Radiator sealant must not be mixed with
the coolant.

The coolant expansion tank is located in the ple-
num chamber under a cover. Slide the cover that
is located below the windshield wipers on the
front passenger's side toward the windshield and
remove the cover > page 237, fig. 158.
> Read the coolant level on the floating gauge for
the expansion tank. The coolant level must be
between the Min and Max markings when the
coolant is cold > fig. 159
Adding coolant
Requirement: there must be a residual amount of
coolant in the expansion tank >@).
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
> Allow the coolant to cool down.
> Place a large, thick towel on the coolant expan-
sion tank cap.
> Unscrew the cap carefully to the left > A\.
> Add coolant with the correct mixture ratio
=> page 237 until the floater gauge reaches the
Max marking.
> Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Screw on the cap securely to the right.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected.

Z\ WARNING
— The engine/motor compartment in any vehi-
cle can be a dangerous area. Switch the igni-
tion off and allow the cooling system to cool
down. Always follow the information found
in > page 235, General information.
— Never open the hood if you can see or hear
steam or coolant escaping from the motor
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the motor
compartment with caution.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store the |>

coolant in the original container and away
from children. There is a risk of poisoning.


@) Note
— Do not add coolant if the expansion tank is
empty. Air could enter the cooling system
and increase the risk of damage. If this is
the case, do not continue driving. See an au-
thorized Audi dealer or authorized Audi
Service Facility for assistance.
— If coolant must be added multiple times
within two months, drive immediately to an
authorized Audi dealer or authorized Audi
Service Facility because there is a risk of
damage.

al information.
Checking the brake fluid level
> Slide the cover that is located below the wind-
shield wipers on the driver's side toward the
windshield and remove the cover.
> Read the brake fluid level on the brake fluid res-
ervoir > page 237, fig. 158. The brake fluid lev-
el must be between the MIN and MAX markings
of.
The brake fluid level is monitored automatically.
Message
EG f) Brakes: stop vehicle and check brake
fluid level
Stop the vehicle and check the brake fluid level.
See an authorized Audi dealer or authorized Audi
Service Facility for assistance.
Changing the brake fluid
Brake fluid should be changed at regular inter-
vals. Have the brake fluid changed by an author-
ized Audi dealer or authorized Audi Service Facili-
ty. The authorized Audi dealer or authorized Audi
Service Facility will inform you of the replace-
ment intervals.

Z\ WARNING
— If the brake fluid level is below the MIN
marking, it can impair the braking effect and
driving safety, which increase the risk of an
accident. Do not continue driving. See an au-
thorized Audi dealer or authorized Audi
Service Facility for assistance.
— If the brake fluid is old, bubbles may form in
the brake system during heavy braking. This
could impair braking performance and driv-
ing safety, which increases the risk of an ac-
cident.
— The brake fluid in your vehicle must meet
the standard VW 501 14 and is available at
an authorized Audi dealer or authorized Au-
di Service Facility. If this brake fluid is not
available, another high-grade brake fluid of
equivalent quality may be used, and it must
meet the U.S. Federal Motor Vehicle Stand-
ard (FMVSS) 116 DOT 4, Class 6.
@) Note
— If the brake fluid level is above the MAX
marking, brake fluid may leak out over the
edge of the reservoir and result in damage
to the vehicle.


— Do not allow any brake fluid to come into
contact with the vehicle paint, because it
will corrode the paint.
Electrical system
If the =] / B or [ml indicator light turns on,
there is a malfunction in the power supply, the
battery, or the vehicle electrical system.
